PUZZLE DEVICE.

Application filed. April 4, 1916.

To all whom it may concern:

Be it known that 1, ROBERT F. CAMPBELL, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Puzzle Devices, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to puzzles or puzzle devices, and the object thereof is to provide an improved device of this class which is designed to amuse and entertain both old and young; a further object being to provide a puzzle device the solution of which is difiicult but may be accomplished by the ex ercise of care and skill in the manipulation thereof.

The invention is fully disclosed in the following specification, of which the accom:

' panying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a plan view of my improved puzzle device with the cover thereof removed; Fig. 2 a transverse sectional view with the cover indicated in dotted lines only; and, Fig. 3 a sectional view of a gravity operated roly-poly device which I cum ploy.

In the practice of my invention I provide a box or casing a which is preferably rectangular in form and provided with a removable cover Z) which is indicated in dotted lines in Fig. 2, but the box or casing a may be round or of any preferred shape.

The bottom of the box or casing is provided centrally thereof with a raised portion 0 which is also circular in form, and which is pyramidical in its construction, or consists of a plurality of stepped portions 0 formed in the construction shown by separate layers of material 0 and in the center of the top member 0 thereof is a recess 0". I also provide a gravity operated roly-poly device 03 which consists of an oblong hollow body portion, cylindrical in cross section and semi-spherical at bothends, and in,

Specification of Letters Patent.

which is placed a ball 0Z which is composed of heavy material, and the body portion is also preferably composed of translucent or transparent material, and this device is placed in the box or casing a, as indicated in the drawing, and the solution of the puzzle consists in manipulating the box or casing with the cover Z) removed so as to lodge the roly-poly device d in the recess 0 in the top of the pyramidical center construction as is also indicated in Fig. 2. This solution is very ditiicult because of the structure of the part c and because of the fact that the ball (Z is free to move around in the casing in which it is placed, and of the further fact that the bottom of the box or casing a is smooth and even throughout and that the roly-poly device is free to move in every direction over the bottom of the box or casing, and the difficulty in manipulating the box or casing so as to pass the roly-poly device up over the separate steps of the raised central portion 0 and lodge said rely-poly device in the central recess 0" thereof. This solution, however, may be accomplished by the exercise of great skill and ingenuity in the manipulation of the device, and while I have shown and described the preferred form or structure of my improved puzzle or puzzle device, my invention is not limited to the details of construction herein shown and described, and changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of the invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A puzzle, comprising a box or case the bottom of which is provided with a central raised portion having downwardly and outwardly inclined sides of a step by step formation, said central raised portion being also provided with a flat top in the center of which is a recess, and a gravity operated roly-poly device placed in said box or case.

2. A. puzzle, comprising a box or case the bottom of which is provided with a central raised portion having downwardly and out- Wardly inclined sides of a step by step foras my invention I have signed my name, in mation, comprising separate layers of difl'erpresence of the subscribing Witnesses, this ent sizes placed one upon another and the 31st day of March, 1916.

top layer being provided with an aperture, ROBERT F. CAMPBELL. 5 and a gravity operated roly-poly device Witnesses:

placed in said box or case. C. E. MULREANY, In testimony that I claim the foregoing H. E. THOMPSON.
